DANIEL DUNSCOMB, OF NEW YORK, N. Y.

DISINFECTANT LAUNDRY BLUING.

SPECIFICATION forming part of Letters Patent No. 259,832, dated June 20, 1882.

Application filed March 3,1882. (No specimens.)

eighty (80) parts, or thereabout, of prussiate blue; ten (10) parts, or thereabout, of carbolic acid; five (5) parts, or thereabout, of borax,

and five (5) parts, or thereabout, of gum-arabic or other adhesive substance. These ingredients aredesigned to be thoroughly mixed together to form a soluble paste that may be afterward molded into cakes or blocks of any convenient size andshape for use; or the said ingredients in the above proportions may be dissolved in water and put up in bottles or.

other suitable vessels and be sold and used as a liquid disinfecting-bluing.

When said compound is formed into blocks or cakes and dried said blocks or cakes are preferably coated with a solution of gum-arabic, gelatine,or other adhesive substance, to betterprevent the evaporation and loss of the carbolic acid from the compound.

This improved compound possesses especial advantages for use in hospitals and sick-rooms where clothing and bedding is exposed to con tact with persons suffering from contagious and infectious diseases, for if a suitable quantity of this compound be added to the water in which the clothes are washed the carbolic acid of the compound will operate to disinfect or destroy the germs of disease with which they are contaminated, while the prussiate blue and borax combinein whitening or bleaching the clothes, their bleaching effects being especially noticeable after the ironing of the clothes, the application ofa' hot iron to the well-washed clothes resulting in making them as white as if bleached by long exposure to the sun and air.

The gum-arabic or other adhesive substance I am aware of Patent No. l51,085,which describes the use of borax and gum-arabic in a starch polish; and I am also aware that it is not new to use carbolic acid in soap, and I do not claim either invention.

What I claim is- 1. A bleaching, bluing. and disinfecting compound consisting of soluble blue, borax, gum-arabic, and a disinfecting agent, in substantially the proportions specified.

. 2. A bleaching, bluing, and disinfecting compound consisting of soluble blue, borax, gum-arabic, and carbolic acid, of substantially the proportion specified, mixed together, dried, and provided withan outer protective coating of some adhesive substance to prevent the evaporation of the carbolic acid, as set forth.
